Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2025-11-15 to 2026-03-15. Excludes option exercises, grants, gifts and tax withholding. Amended filings replace the originals; joint filings count once. Foreign private issuers do not file Form 4. Many insider sales are pre-scheduled (10b5-1 plans) and are not by themselves a sign of wrongdoing.

Verified excerpt

"As discussed in Note 1 to the financial statements, the Company has incurred significant operating losses since inception, expects to incur significant operating losses for the foreseeable future and has stated that substantial doubt exists about the Company's ability to continue as a going concern."

Quoted from the filing. Source

What this means

The filing states that substantial doubt exists about the company's ability to continue as a going concern: it may not have enough cash to last the next 12 months. Expect dilution, debt deals or worse. An auditor's going-concern paragraph is the strongest form of this warning.

Going-concern opinion issued by: Ernst & Young LLP
